PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms utilize the same resolution source and logic for determining the outcome of the markets, including handling of postponements, cancellations, and ties.Primary resolution logic: Official MLB statistics (mlb.com)

Core resolution logic:

  • The winner of the game determines the resolution of the 'Houston Astros vs. Philadelphia Phillies' market.
  • A run scored in the first inning by either team determines the resolution of the 'Will there be a run scored in the first inning?' market.
  • If the game is postponed, the market remains open until completion.
  • If the game is canceled or ends in a tie, the market resolves 50-50.

Edge cases & clarifications:

  • Postponement: The market will remain open until the game is completed, regardless of the reason for the postponement.
  • Cancellation: If the game is canceled with no makeup game, the market will resolve 50-50.
  • Tie Game: If the game ends in a tie, the market will resolve 50-50.
  • Delayed Reporting: If official statistics are not published within 24 hours, a consensus of credible reporting will be used.
Timing: Resolution will occur after the official completion of the game and publication of final statistics, or within 24 hours if credible reporting is necessary.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Frequently asked questions

Prediction market odds, like those found on Polymarket and Predict, often reflect the wisdom of the crowd, potentially offering a different perspective than traditional sportsbooks. Sportsbooks set lines based on their own models and aim to profit from margins, while this market is driven by individuals wagering their own capital. This can lead to discrepancies, especially when public sentiment strongly diverges from expert analysis. While sportsbooks may initially set odds based on team statistics and expert opinions, this market can quickly adjust to incorporate new information and changing perceptions about the series. The current volume of $470,719 indicates active trading and price discovery.
